●Safety Connect is available beginning Fall 2009 on select Lexus models. Contact with
the Safety Connect response center is dependent upon the telematics device being in
operative condition, cellular connection availability, and GP S satellite signal reception,
which can limit the ability to reach the response center or receive emergency service
support. Enrollment and Telematics Subscr iption Service Agreement required. A vari-
ety of subscription terms is available; charges vary by subscription term selected.
●Automatic Collision Notification, Emergenc y Assistance and Stolen Vehicle Location
will function in the United States, including Hawaii and Alaska, and in Canada, and
Enhanced Roadside Assistance will function in the United States (except Hawaii) and in
Canada. No Safety Connect services will function outside of the United States in coun-
tries other than Canada.
●Safety Connect services are not subject to section 255 of the Telecommunications Act
and the device is not TTY compatible.

■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power radio\
transmitter and receiver. It receives and also sends out radio frequency (RF)
signals.
In August 1996, the Federal Commu nications Commission (FCC) adopted
RF exposure guidelines with safety levels for mobile wireless phones. Those
guidelines are consistent with the safe ty standards previously set by the fol-
lowing U.S. and internat ional standards bodies.
●ANSI (American National Stan dards Institute) C95.1 [1992]
●NCRP (National Council on Radiation Protection and Measurement)
Report 86 [1986]
●ICNIRP (International Commission on Non-Ionizing Radiation Protection)
[1996]
Those standards were based on comprehensive and periodic evaluations of
the relevant scientific literature. Over 120 scientists, engineers, and physi-
cians from universities, and governme nt health agencies and industries
reviewed the available body of rese arch to develop the ANSI Standard
(C95.1).
The design of Safety Connect complies wi th the FCC guidelines in addition to
those standards.

●Working from top to bott
om, liberally apply water to the vehicle body, wheel
wells and underside of the vehicl e to remove any dirt and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wa sh soap and rinse thoroughly with
water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is cool.
■Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface scratches
caused in a car wash etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.
●The restoration time differs depending on the depth of the scratch and outside tem-
perature. The restoration ti me may become shorter when the coating is warmed by
applying warm water.
●Deep scratches caused by keys, coins, etc. cannot be restored.
●Do not use wax that contain abrasives.
■Automatic car washes
●Before washing the vehicle:
• Fold the mirrors
• Turn off the power back door
Start washing from the front of the vehicle. Extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface and harm your
vehicle’s paint.
●Rear spoiler may not be wash able in some automatic car washes. There may also be an
increased risk of damage to vehicle.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the windows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed prop-
erly.
